United States Patent 3,363,323 MULTIPLE PACKAGING PARTITION MEMBER Richard E. Paige, 411 E. 57th St., New York, N.Y. 10022, and Hans L. Levi, 177 White Plains Road, Tarrytown, N.Y. 19591 Filed Oct. 15, 1%4, Ser. No. 403,982 6 Claims. (Cl. 229) This invention relates to packaging members for dividing the interior of a container into compartments or pockets for various objects to be stored or shipped and this invention is particularly an improvement over the pack aging member disclosed in United States Letters Patent 2,563,132.

However, the partitions shown in this patent have a tendency to snake or twist around in the container thereby becoming displaced and furthermore do not hold their position with sufficient dependability to allow quick insertion of the object. Again, the partitions in this patent extended only part way down to the floor which is objectionable.

It is accordingly a principal object of the present invention to provide a one-piece single face paper partition that is sutficiently wide to prevent twisting in the box and that extends down to the floor of the container.

Another object of the present invention is to provide a packaging assembly for a container that conveniently accommodates a dozen objects or two dozen objects which is desirable.

A further object is to provide a packaging assembly that effectively separates object from object, such as, glass from glass.

Still another object is to provide a partition assembly that is attractive in appearance and that is susceptible to quick and effective packaging.

Yet another object of the invention is to provide a packaging assembly adapted to serve as partitions in a carton or the like, and having such formation as to occupy a minimum of space when stacked, but so constructed that it can be easily and quickly set up in operative position with respect to the container which is to receive it.

Another object is to provide such a member constructed entirely of sheet material and having initially the shape of a flat blank with scored lines in the surface thereof, delineating portions to form the pockets and capable of being folded and bent along said lines to provide the finished product.

Still another object is to provide such a member by fashioning a blank having the necessary outline or shape, out of sheet material that is flexible in character; hence, the parts can be readily adjusted for practical use; and further when the blank is folded to move all parts into their proper final positions, said par-ts take on a reinforcing effect that gives full strength and sufficient rigidity to enable them to offer most effective resistance to any force, such as a jar or shock, that might bring about a collision between the objects which said member is designed to protect against such impacts, and thus eliminate all risk of breaking, abrading and other damage.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a top perspective view of a box or carton with a partitioning assembly embodying my invention inserted therein and supporting drinking glasses in separated relationship.

FIG. 2 is a top perspective view of the partitioning :assembly removed from the box, without the drinking glasses.

FIG. 3 is a top perspective view of a fragment of the box and partitioning assembly of FIG. 1.

FIG. 8 is a top perspective view of a fragment of the blank from which the partitioning assembly has been formed, parts being shown in folded condition and parts being shown broken away, supported drinking glasses being shown in dash lines, on an enlarged scale.

FIG. 9 is a perspective view of a roll of blanks for forming the partitioning assemblies of FIG. 1, the blanks being partly shaped and scored.

FIG. 10 is a top perspective view of a modified form of partitioning member for holding a square shaped bottle.

FIG. 11 is a plan view of the blank from which the partitioning member of FIG. 10 has been made.

Partitions for boxes and cartons wherein drinking glasses, jars, bottles, and other articles are packed are often made of strips of cardboard and other material running lengthwise and across the container, to form pockets or compartments, each to receive a single one of said articles to isolate it and protect it from the others. The separate strips have transverse slits in their longitudinal edges so that they can be assembled to form a reticulated unit. Such units can be collapsed and stored away, but in that state they each present several layers in thicknesses, and occupy a great deal of space, especially when they are handled in Stacks.

My invention obviates this disadvantage because the partition member is fashioned out of a single layer of sheet material and has originally the form of a flat blank of only one layer in thickness. It is appropriately scored or creased with lines which lines or creases define parts which enable the blank to be bent into the configuration which assures the results desired. The device is thus simple, effective and quite inexpensive, can be instantly set up by any shipping roorn clerk, and requires a minimum of space for stacking and storing.

Referring now in detail to the drawings, in FIG. 1 a rectangular packing box or carton 10 is shown with side walls 12, 12 and end walls 14, 14 and is open at the top. End flaps 15 and side flaps 17, respectively, are provided for closing the top of the box.

According to the present invention, a one-piece partitioning assembly or structure 16 is provided for keeping the articles such as the drinking glasses 18 separated from each other. The partitioning assembly is formed of flexible sheet material, preferably single face corrugated paper, but it will be understood that box board or cardboard might be used if desired.

The partitioning assembly 16 is divided into sections or units 29 fashioned out of a flat rectangular blank or strip 22 shown in FIG. 8, having a smooth face 24 and a corrugated face 26. The blank or strip on its smooth noncorrugated face is formed with transverse crease or score lines 28 at spaced intervals thercalong. The material between the lines 23 define the sections or units 20. A pair of opposed flaps 3t), 3t! is formed on the blank midway the ends of each section extending laterally, and inwardly of each flap there is a curved crease or score line 32 on the smooth face of the blank.

At each section Or unit 20, on the smooth face 24 of the blank, at the center of the section, there is formed a slit 34 extending longitudinally of the blank, and at each end of the slit there is a cross slit 36, shorter than the slit 34-. A curved crease or score line 38 is formed in the smooth face 24 of the blank connecting each pair of ends of the cross slits 36. When the section or unit is folded along the crease lines 28 a partly completed section or unit 30 is formed, having side Walls 46], 40 and dome-shaped top wall 42. The operation of creasing the material along the curved lines 32 forms recesses at the ends of the section or unit, the recesses constituting compartments 44. The flaps 3t) and the material of the blank inwardly thereof constitute the inner and side walls of said compartments 44, said walls extending to the bottom edge of the assembly for seating on the bottom wall of the box or carton lltl. The operation of creasing the material along the curved lines 38 forms a central cylindrical opening constituting a compartment 4-6 in the top wall of the section, the material between the creases forming curved opposed end walls 48 for the compartment.

The blank is creased or bent along the transverse lines 28 into curved formation as shown in FIG. 8 whereby the sections 2t) become juxtaposed. The invention contemplates a ribbon of such partitioning assemblies in the form of a roll 50 mounted on a spool 52 as shown in FIG. 9. If partitioning assemblies containing four sections each with three compartments each for supporting a dozen glasses is desired, then every fifth line can be a tear line 54 to facilitate tearing of the blank at this point so as to provide an assembly with four sections to be placed in the container.

When the partitioning assembly 16 is inserted into a packaging box or carton 10, the side walls 4-0 of the sections 20 engage end walls of the box and the edges of the end compartments walls 30 engage the side walls of the carton so that no displacement can take place either longitudinally or transversely of the box. The end compartments 44 are in longitudinal alignment, with each other, and the central compartments 46 are in longitudinal alignment with each other. The glasses in each section are in crosswise alignment. Furthermore, the glasses in the central compartments are engaged on all sides by the side walls 40 and end wall 42 so that they are securely held against any accidental displacement. Similarly, the glasses in the end compartments 44 are snugly engaged by the side and inner Walls of the compartments and by the side walls of the box.

In FIGS. and 11, a modified form of partitioning member is shown for holding and separating square shaped articles, such as bottles. The flat ribbon shaped blank 22 for forming the member 20 is shown in FIG. 11 and is formed with a series of tear or score lines 28 at spaced intervals therealong. Between adjacent lines 28', flaps 30 extending laterally of the blank are formed, and inwardly of the flaps the smooth face side of the blank is formed with slanting crease or score lines 32' extending toward the center of the area between the tear lines. At the center of said area, there is a slit 34 extending longitudinally of the blank, and at each end of the slit there is a cross slit 36 shorter than the slit 24. A slanting crease or score line 38 is formed in the smooth face 24 or the blank connecting the slit 36 with a longitudinal crease or score line 54 closely spaced from a similarly extending crease line 5n, the ends of which connect with the slanting crease lines 32.

When the blank 22. shown in FIG. 11 is folded along its crease lines, a partitioning section 20 as shown in FIG. 10 results. This partitioning section 20' has side walls 40, 4t), end walls 3%) and d0ubled-wall extensions 58 at each end formed by the flaps 3t) and the material of the blank inwardly of said flaps. A central opening or compartment 46 is formed for supporting and separating a square shaped bottle or the like from other similarly shaped bottles.

By reasons of this construction, drinking glass is effectively separated from drinking glass. The single face corrugated paper can be made in continuous lengths on a machine, the lengths die cut, the lengths folded by a machine, and the folded job inserted right into the set up box. The curvature of the bodies of the sections make for an attractive partitioning device.

While we have illustrated and described the preferred embodiments of our invention, it is to be understood that We do not limit ourselves to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
